The network processor incorporates a processor and a number of coprocessors that can be connected to the processor either Directly or using a shared bus This paper presents the proposal and development of a reconfigurable crossbar switch architecture for network processors. Its main purpose is to increase the performance, and flexibility for environments with multiprocessors and computer clusters. The results include VHDL simulation of Crossbar Switch and the use of it in a broadcast function implementation, found in message passing support middleware. This reconfigurable crossbar Switch used in Network Processor to connect the various circuits which are used to perform the various task.
